My 2009 HHR panel has a dead battery after sitting idle for only three or four days. It has been to the dealership twice and they can't find anything wrong. I believe it is a phantom drain on the battery. Yesterday this happened for the third time and I had to call road service to jump start it. I desparately need a solution to this problem. I found some information on a forum which indicates a solution might be available, but it only applies to 2007vehicles: "Recommendation/Instructions:
Note: Only apply the information to 2007 model year vehicles. A separate PI (Preliminary Investigation) has been created for the 08-09 model year
If you experience a vehicle that has an intermittent battery draw, please follow the instructions below and then review the template below that lists all related PI's and Bulletins. If it becomes necessary to contact Technical Assistance, please record the results for all the PI's and Bulletins that apply to your vehicle prior to calling."
One question is, where can I find these PI's and bulletins for the 08-09 models? My main question is, what is the solution to this problem?
